Apple's Wednesday Pro Tip of the Week--Removing Toolbar Icons

is located on this Apple web page. It states,

To remove an icon from the toolbar, you don’t have to go digging through the View menu to get the Customize Toolbar dialog. Instead, just hold the Command key, click on the icon, and simply drag it off the toolbar. When you release the mouse button the icon will disappear in a puff of smoke.
